Hi Neill

Per the above, your computer is missing a critical OS X file. Do you have another machine with OS X Leopard installed? If you do, I'll give instructions for copying that file from one machine to another.
If not:
If you have another browser installed, such as Firefox, download and run the 10.5.1 Update. If you don't have access to another browser, I suggest you pay a visit to an Apple Store or a certified Apple Tech location to assist you with these suggestions.
After the Install/restart of the Update, "repair permissions" etc. Do not use the computer while the update is running. Restart Safari. (you might get lucky if the update adds the file to your system).
If no go, then I suggest reinstalling the OS using the Archive and Install method.
